Low Pressure Switching Monitor LPS

The Low Pressure Switching (LPS) Monitor was engineered for monitoring low differential pressures in various process applications. The switching function allows for independent high and low pressure alarms to be adjusted from the front panel. The digital LED display clearly indicates the process pressure and front panel status lights indicate the condition of the alarm state by showing green when in limits and red when an alarm limit is exceeded. The time delay circuit allows customization of the unit response to prevent intermittent tripping due to transient pressure fluctuations.
